SLOPE, AGGREGATE EXPENDITURES LINE: The positive slope of the aggregate expenditures line is the sum of the marginal propensity to consume (MPC), marginal propensity to invest (MPI), and marginal propensity for government purchases (MPG), less the marginal propensity to import (MPM). This slope is greater than zero but less than one, reflecting induced expenditures by the four macroeconomic sectors (household, business, government, and foreign). The slope of the aggregate expenditures line determines the magnitude of the multiplier process.

THREE-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes the three domestic sectors, the household sector, the business sector, and the government sector. This Keynesian model variation adds the government sector (or public sector) to the household and business sectors that make up the two-sector model. This model enables an analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the C + I + G line and the 45-degree line. Two related models are the two-sector Keynesian model and the four-sector Keynesian model.
